9.9.9.9

Other public DNS server is OpenDNS

208.67.222.222
208.67.220.220

All these DNS servers have good connectivity in india. I get ~65 ping to these serves, that is normal for indian servers.

On linux you can configure DNS server by editing file

vi /etc/resolv.conf

Add

nameserver 1.1.1.1
nameserver 8.8.8.8
nameserver 9.9.9.9
